"One of the biggest reasons why detachables are growing so fast is because end users are seeing those devices as PC replacements," said Jean Philippe Bouchard -- Research Director, Tablets, at IDC.

"We believe Apple sold just over two million iPad Pros while Microsoft sold around 1.6 million Surface devices, a majority of which were Surface Pro and not the more affordable Surface 3. With these results, it's clear that price is not the most important feature considered when acquiring a detachable â€“ performance is," Bouchard added.

As per the IDC, Apple tops the 2015 chart with 24.5% global tablet market share, while arch rival Samsung comes a distant second with 16.2% share.Lenovo (5.4%), Asus (3.4%) and Huawei (3.1%) are placed at third, fourth and fifth positions, respectively.

Among the top five tablet vendors Lenovo and Huawei were only two witnessed growth. The former's market share grew by a modest 0.4%, whereas the latter grew a staggering 116%.
